Answer:
[tex]0.30molNH_3[/tex]
Explanation:
Hello there!
In this case, since the reaction for the formation of ammonia is:
[tex]3H_2+N_2\rightarrow 2NH_3[/tex]
We can evidence the 1:2 mole ratio of nitrogen gas to ammonia; therefore, the appropriate stoichiometric setup for the calculation of the moles of the latter turns out to be:
[tex]0.15molN_2*\frac{2molNH_3}{1molN_2}[/tex]
And the result is:
[tex]0.30molNH_3[/tex]

40 g of NaCl is added to 1500 g of water. What is the molality of the resulting
solution?
Molality = moles of solute/mass (in kg) of solvent
The solute here is NaCl, of which you have 40 g or 40/58.4428 = 0.6844 moles NaCl.
The solvent here is water, of which you have 1500 g or 1.500 kg H2O.
The molality of the resulting solution would thus be 0.6844 moles NaCl/1.500 kg H2O = 0.4562 mol/kg.
If you have to consider sig figs, then your final answer would have one sig fig (40 g has one sig fig). In that case, your final answer would be 0.5 mol/kg.

if 0.200 moles of AgNO3 react with 0.155 moles of H2SO4 according to this UNBALANCED equation below, how many grams of AgSO4 could be formed? AgNO3+H2SO4->Ag2SO4+HNO3
Answer:
62.36 g
Explanation:
AgNO3 + H2SO4 - > Ag2SO4 + HNO3
The balanced equation is given as;
2AgNO3 + H2SO4 → Ag2SO4 + 2HNO3
From the equation;
2 mol of AgNO3 reacts with 1 mol of H2SO4
if 0.200 moles of AgNO3 react with 0.155 moles of H2SO4
The limiting reactant us AgNO3 as it determines the amount of products to be formed.
2 mol of AgNO3 produces 1 mol of Ag2SO4
0.2 mol of AgNO3 would produce x mol of Ag2SO4
Solving for x;
2 = 2
0.2 = x
x =0.2 * 2/ 2 = 0.2 mol
Converting moles to mass;
Mass = Number of Moles * Molar mass
Mass = 0.2 mol * 311.8 g/mol
Mass = 62.36 g

2. What happens to the temperature of air when it is compressed?
Explanation:
the pressure and temperature of the air increase
reason:
the volume of the space containing air decreases.
Explanation:
Whether you know it or not, compressed air is involved in every aspect of our lives, from the balloons at your birthday party to the air in the tires of our cars and bicycles. It was probably even used when making the phone, tablet or computer you’re viewing this on.
The main ingredient of compressed air is - you guessed it! - air. Air is a gas mixture, which means it consists of many different gases. Primarily these are nitrogen (78%) and oxygen (21%).
The temperature of the air is directly proportional to the mean kinetic energy of these molecules. This means that the air temperature will be high if the mean kinetic energy is large (and the air molecules move faster). The temperature will be low when the kinetic energy is small.
Compressing the air makes the molecules move more rapidly, which increases the temperature. This phenomenon is called “heat of compression”. Compressing air is literally to force it into a smaller space and as a result bringing the molecules closer to each other. The energy that gets released when doing this is equal to the energy required to force the air into the smaller space. In other words, it stores the energy for future use.
The value of Kp for the reaction 2 A(g) + B(g) + 3 C(g) → 2 D(g) + E(g) is 18530 at a particular temperature. What would be the value of Kp for the reaction 2 D(g) + E(g) → 2 A(g) + B(g) + 3 C(g)?
Answer:
[tex]Kp2=5.3967x10^{-5}[/tex]
Explanation:
Hello there!
In this case, since the Kp for the first reaction is given, according to the following equilibrium expression:
[tex]Kp=\frac{p_D^2p_E}{p_A^2p_Bp_C^3} =18530[/tex]
However, since the second reaction stands for the reverse of the initial one, the equilibrium expression would be:
[tex]Kp_2=Kp=\frac{p_A^2p_Bp_C^3}{p_D^2p_E}[/tex]
And therefore its Kp the inverse of the aforementioned one:
[tex]Kp2=1/18530\\\\Kp2=5.3967x10^{-5}[/tex]

Suppose Rutherford's lab was 10 meters (m) long and the speed of an alpha particle is 3.0x10^8 meters per second (m/s). How much time would he plan on the alpha particles taking to move from the alpha particle source to the gold foil target? Write it in a mathematical equation
Answer:
t = d/v , 33.3 ns
Explanation:
Since distance, d = vt where v = speed and t = time taken to cover the distance.
Since the distance, d covered by the alpha particle is the length of Rutherford's lab which is 10 m long and the speed of the alpha particle is v = 3 × 10⁸ m/s, the time, t it takes the alpha particle to move from the alpha particle source to the gold foil target is thus
t = d/v
= 10 m/3 × 10⁸ m/s
= 10/3 × 10⁻⁸ s
= 3.33 × 10⁻⁸ s
= 33.3 × 10⁻⁹ s
= 33.3 ns

Explanation:
Antacid has a pH of 11. What does that tell you about its concentration of hydrogen ions? What does that tell you about its concentration of hydroxide ions?
Answer: The concentration of hydrogen ions is [tex]10^{-11}M[/tex] and the concentration of hydroxide ions is [tex]10^{-3}M[/tex]. Thus the concentration of hydroxide ions is more than the concentration of hydrogen ions.
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
[tex]pH=-\log [H^+][/tex]
[tex]pOH=-\log[OH^-][/tex]
Putting in the values:
[tex]11=-\log[H^+][/tex]
[tex][H^+]=10^{-11}M[/tex]
[tex]pH+pOH=14[/tex]
[tex]pOH=14-11=3[/tex]
[tex]3=-log[OH^-][/tex]
[tex][OH^-]=10^{-3}M[/tex]
Thus the concentration of hydroxide ions is more than the concentration of hydrogen ions.
